I'm soliciting comments regarding my reasoning and choices for EI on an O-360 with the dual mag.
My intention is to remove this troublesome component entirely. Also, I do not believe that a custom built *******ized single-mag to fit in that space is really a good viable long-term option either. So that leads me to a dual EI setup.
Further, I have heard some comments about the drive for the dual mag being a problem source as well as the mag itself. Specifically, I found a couple of bits of information regarding occurrences of either/both pins shearing and/or drive gear teeth stripping either way leading to parts in the accessory case, in turn leading to a rapid failure of the engine. Any truth to this? Does this mean to eliminate that issue I should not drive anything (such as an emag) from that drive?
I found Lightspeed, Electroair, G3i, Emag, Protek, and Slick with EI solutions. G3i depends on existing mags, Emag solution has been vaporware for years, and Slick doesn't have a dual mag solution. The Protek solution apparently uses a single pick-up and cable to fire both sides. To me this appears to be a single point of failure that would take out my ignition entirely. Physical damage to the pick up, cable chafe, manufacturing defects, excessive heat or moisture or any number of things could take this out. I'm just not comfortable with it.
This appears to leave Lightspeed and Electroair. Lightspeed can be driven by two completely separate and independent crank fired sensors, eliminating anything being driven by the current mag drive gears. Electroair, suggests one side driven off a crank sensor, the other from a mag timing housing on the mag drive pad. This would re-use the drive gear and impulse coupling from my current dual mag.
I'm leaning towards the Lightspeed setup currently. Love to hear other points of view.
